Application May '7, 1936, Serial No. 78,359

3 Claims.

The present invention relates to roller skates and has for its primary object to provide a two roller'skate which can be readily adjusted to t various sizes of shoes and to properly dispose the rollers with respect to the foot to provide for proper balance.

Another object of the present invention is to provide a durable skate which may be economically manufactured and readily assembled. To this end the heel and toe plates are provided with means permanently secured thereto for supporting rollers on the plates, the means for supporting the roll-ers being constructed so as to slidably engage a channel shaped body to permit lengthwise adjustment with respect thereto, and being provided with clamping means for securing the roller supports and plates with respect to the channel'after the adjustments have been made.

Another object of the present invention is to provide in combination with a roller skate means for securing the toe plate to the sole of a shoe, and more particularly, a means which makes it posl sible to use a skate on either the right or left foot interchangeably. To this end the toe plate of each skate is provided with two sole clamps which are individually adjustable.

With'the above and other ends in view the invention consists in matters more particularly set forth with reference to the accompanying drawing, in which Figure 1 is a plan of the skate;

Fig. 2 is a side elevation; and

Figs. 3, 4, 5, and 6 are sections taken on the lines 3-3, 4 4, 5 5 and 6-6 respectively of Fig. l.

Like characters of reference are employed throughout to designate corresponding parts.

The numeral I, designates the heel plate of the skate, the plate I having a pair of upstanding heel engaging parts 2 provided with slots for the reception of a strap in a manner already known in the art and therefore not shown here. A pair of spaced apart arms 3 are provided beneath the plate `I and each arm has an outwardly directed flange l secured to the heel plate by rivets 5. In some cases, the rivets 5 will be dispensed with and the ilanges l will be welded to the plate. The outer ends of the arms 3 are united by a shaft 6 upon which is rotatably mounted a roller l.

The arms 3 are formed, preferably by stamping, of sheet metal and they are provided with integral forwardly extending walls 8 with inwardly projecting danges SJ at their lower edges. Each flange 8 has a depending lug Ill and a clamping bolt li is extended between the lugs. An elon- (ol. 28o-11.26)

gated channel-shaped body I2 extends between the arms 3 and the walls 8 and is engaged at its top by the plate I and at its bottom by the flanges 9. The plate I is thus slidably supported on the channel body I2 and may be secured against slidable movement with respect thereto by tightening the clamping bolt Ii so as to draw the walls 8 into tight irictional engagement with the sides of the body I2.

The numeral I3 designates the toe plate of the skate. Secured beneath the toe plate are two spaced apart arms 3a supporting an axle 6a and a roller 'Ia in the manner above described. The arms 3a have integral walls Sw with inwardly directed flanges 9a and lugs lila receiving the clamping bolt Ila. The end of the channel body I2 is received between the walls 8a and arms 3a, and between the bottom surface of the plate I3 and the iianges 9a. These parts may be secured against relative movement by tightening the bolt IIa.

The toe plate I3 has a transversely extending slot Ill and adjacent to each end of the slot is a bolt I5. Sole engaging elements I6 have slots I'I through which the bolts I5 extend and clamping nuts I8 are provided on the bolts to secure the elements I6 with respect to the plate. Each element I6 has a stud I9 projecting into the slot I4 to prevent its turning around its respective bolt. Obviously, either clamping element I6 may be adjusted without disturbing the other.

Although a specific embodiment of the invention has been illustrated and described it will be understood that various changes may be made within the scope of the appended claims without departing from the spirit of the invention, and such changes are contemplated.

What I claim is:-

1. A roller skate comprising a rigid body, a

plate, a pair of arms depending from said plate and supporting a roller, said arms being spaced apart to engage opposite sides of said rigid body which extends therebetween, said arms having inwardly directed flanges integral therewith and engaging the underside of said rigid body, and means carried by said flanges for clamping said arms against said rigid body.

2. A roller skate comprising a rigid channel member having a pair of parallel side walls and a web portion uniting said side walls, a plate, a pair of arms depending from said plate and engaging opposite sides of said channel member, means on said arms extending inwardly between the arms and engaging the web portion of the channel member to retain the upper edges of the side walls in Contact With said plate, and means for clamping said arms against the channel member to prevent relative movement between the channel member and plate.

3. A roller skate comprising a rigid body, a plate, a pair of arms depending from said plate and supporting a roller, said arms being spaced pending ears on said anges, and a set screw 5 extending between said ears.
